This study is a descriptive correlation that attempts to determine the mediating effect of self-efficacy on the relationship between university life stress and smartphone overuse. A total of 201 university students attending universities within Jeonbuk were evaluated using self-reported questionnaires from April 10 to May 10, 2017. The demographic characteristics, university life stress, self-efficacy, and smartphone overuse were analyzed by descriptive statistical analysis. The difference in smartphone overuse by demographic characteristics was analyzed by t-tests and ANOVA with Scheffe's post hoc test, and the correlation between variables was evaluated by Pearson's correlation coefficient. The mediating effect of self-efficacy was the 3-step multiple regression statistics of Baron and Kenny, and the statistical significance of the mediating effect was analyzed by the Sobel test. Self-efficacy had a partial mediating effect in the relationship between university life stress and smartphone overuse. In addition, the risk of smartphone overuse increased among university freshmen, with many using smartphones for more than 4 or 6 hours per day. The result of this study are expected to be useful as basic data for the development of a program to prevent excessive smartphone use by university students.

This paper investigates the effect of Team Member Exchange Quality (TMX) and technology management education on innovative behavior mediating effects of Empowerment. Innovation behavior is necessary for the continuous innovation of the organization. To that end, this paper investigates the relationship among TMX, technology management education, empowerment, and innovation behavior. Independent variables are TMX and technology management education; dependent variable is innovative behavior; and mediating variable is empowerment. The hypotheses of this paper are as follows. First, team members with a high quality of TMX will generate more innovation behavior. Second, innovation behavior will be created if team members receive a lot of technology innovation education. Third, empowerment will have a mediating effect on the relationship between TMX, technology innovation education and innovation behavior. To test these hypotheses, questionnaires were distributed and thoroughly analyzed using correlation analysis, multiple regression, and mediating effect analysis. Until now, there have been many previous studies investigating innovative behavior; however, this paper is still meaningful in that this study focused on the effects of TMX and Technology management education on innovative behavior mediating the effects of empowerment.

Abstract The purpose of this study is to analyze the changes in job satisfaction and turnover intention according to the level of Emotional labor and the mediating effect in dental hygienists. Higher levels of emotional labor resulted in lower levels of job satisfaction, as well as higher levels of turnover intention. We used the logistic regression analysis to compare change of job satisfaction, turnover intention according to the level of emotional labor. In logistic regression analyses, social support was the largest mediating factor between emotional labor and job satisfaction and the odds(Likely to with low job satisfaction) was down by 16% after adjustment for supervisor, colleague. In case of turnover intention, largest mediating factor were drinking, physical condition, supervisor, colleague and the odds(Likely to with high turnover intention) was down by 52% after adjustment for mediating factors. The results of this study were as follows. Emotional labor was negatively impact on job satisfaction and turnover intention. To increase the job satisfaction and lower the turnover intention, it is necessary to do more efforts to improve social support(supervisor and colleague) and management personal factor(drinking, physical condition) for the dental hygienists should be made to reduce such negative effects.

The general aspects for the future warfare shows that the concept of firepower and maneuver centric warfare has been replacing with that of information and knowledge centric warfare. Thus, some developed countries are now trying to establish the information systems to perform intelligent warfare and innovate defense operations. The C4I(Command, Control, Communication, Computers and Intelligence for the Warrior) systems make it possible to do modern and systematic war operations. The basic idea of this study is to investigate how TAM(Technology Acceptance Model) can explain the acceptance behavior in military organizations. Because TAM is inadequate in explaining the acceptance processes forcomplex technologies and strict organizations, a revised research model based upon TAM was developed in order to assess the usage of the C4I system. The purpose of this study is to investigate factors affecting the usage of C4I in the Korean Army. The research model, based upon TAM, was extended through a belief construct such as self-efficacy as one of mediating variables. The self-efficacy has been used as a mediating variable for technology acceptance, and the variable was included in the research model. The external variables were selected on the basis of previous research. The external variables can be classified into following: 1) technological, 2) organizational, and 3) environmental factors on the basis of TOE(Technology-Organization-Environment) framework. The technological factor includes the information quality and the task-technology fitness. The organizational factor includes the influence of senior colleagues. The environmental factor includes the education/train data. The external variables are considered very important for explaining the behavior patterns of information technology or systems. A structured questionnaire was developed and administrated to those who were using the C4I system. Total 329 data were used for statistical data analyses. A confirmatory factor analysis and structured equation model were used as main statistical methods. Model fitness Indexes for measurement and structured models were verified before all 18 hypotheses were tested. This study shows that the perceived usefulness and the self-efficacy played their roles more than the perceived ease of use did in TAM. In military organizations, the perceived usefulness showed its mediating effects between external variables and dependent variable, but the perceived ease of use did not. These results imply that the perceived usefulness can explain the acceptance processes better than the perceived ease of use in the army. The self-efficacy was also used as one of the three mediating variables, and showed its mediating effects in explaining the acceptance processes. Such results also show that the self-efficacy can be selected as one possible belief construct in TAM. The perceived usefulness was influenced by such factors as senior colleagues, the information quality, and the task-technology fitness. The self-efficacy was affected by education/train and task-technology fitness. The actual usage of C4I was influenced not by the perceived ease of use but by the perceived usefulness and selfefficacy. This study suggests the followings: (1) An extended TAM can be applied to such strict organizations as the army; (2) Three mediation variables are included in the research model and tested at real situations; and (3) Several other implications are discussed.
